RAILROAD-RAIL.l

SPECIFICATION forming part of Letters Patent No. 322,412, dated July 21, 1885.

Application filed January 12, 1885.

To aZZ whom t may concern:

Be it known that l, FREDERICK W. BRooKs, of Oak Grove, in the county of Dodge, and in the State of Visconsin, have invented certain new and useful Improvements in Railroad- Rails; and I do hereby declare that the following is a full, clear, and exact description thereof. f

My invention has especial reference to rails used in the construction of steanrrailroads; and it consists in certain peculiarities of construction, as will be more fully set forth hereinafter.

In the drawings, Figure l is a top View of a rail-section embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical transverse section thereof, and Fig. 4 is a like sectional view showing a Inodilied construction.

A is the base or foot of the rail, and B the web, the two being preferably formed integral with each other, and the web having a vertical central longitudinal groove, B, extending from the top half-way down the web or more. Gis the tread, formed independently of the web B, and having a downward depending central longitudinal flange, C, its entire length, adapted to fit in the grooves B of the websec tions, as shown. e

The treads C C are disposed so as to break joints with the foot and web sections A B, as shown, and each end of every tread is cut at an angle to its length of, say, forty-iive degrees, so that the successive tread sections C will mat-ch when pnt together, as shown at c c, and preferably about midway of the length of the At intervals along the length of the web-sections B the same is perforated from each side, the slots b on one side being much longer than the slots b on the opposite side, and both slots opening into the groove B', aforenamed. The ange C of the tread-sections C is cutaway on one side its entire length, forming a groove, C2, with flat top and inclined side, as shown in Figs. 3 and 4.

The preferred method of fastening the several sections of my device together is illus trated in Fig. 3. y

D is a bolt, one end of which, d, is screwthreaded, while the other end, D', is bent intoV a hook having an inclined end or face,I d, which is cut at the same angle that the groove (No model.)

G2 in the tread-flange C is, so that the hooked end will rest smoothly upon the said flange, as shown in Fig. 3, the parts being tightened to place by means of the nut E, workingon the screw-threaded end (l of the bolt, and preferably having a washer, e, interposed between the web B of the rail and the bearing-face of the said nut E. It will thus be seen that when the several parts of my device are put together, as shown, the tread C will be drawn down tightly on the web-sections B B byturning the nut E, which draws on the hook bolt D D', and as the pressure is increased the inclined face d of the hook will draw down on the inclined face of the groove C2 in the side of the tread-ange C', thus holding all the parts firmly together without the necessity of using any ish-plates or other securing devices.

In Fig. 4 I have shown a modiication'of the foregoing device, but one working on the same principle. In this form the groove B in the web sections B is preferably deeper, and I have but one side of the web perforated, using only the slots `b to communicate with the groove B, but make these slots screwthreaded. I use a short bolt, D, wholly screwthreaded, and dispense with the nut, though I may use one or more of the washers e, as found necessary.

If desired, I may niakethe upper surfaces of the two parts of the web-sections B rounded, as shown at b2 b2, andy round out at the under surface of the tread C to correspond, as shown at c' c', and this construction I may apply to Y the form shown in Fig. 3, if preferred, as wel-l as to the form shown in Fig. 4, and correspondingly I may, if desired, make the top surfaces of the web-section B and under surface of the tread C dat, with the form of bolt shown in Fig. 4, as well as with the style shown in Fig.

3. Vith the form shown in Fig. 4, by simply turning the bolt D a downward pressure is exerted on the tread-liange C' by the contact of the bolt end against the inclined groove G2, as before described.

Having thus described my invention, what 1 claim as new, and desire to secure by Let.

l.. In a railroad-rail, the combination of the foot and web section A B, having longitudinal vertical groove B', and side perforations communicating with said groove, with the tread- I OO section C,having depending longitudinal flange C,provided With an inclined-faced side groove,

C2, and bolt D, adapted to bear against the inolined side of the groove C2, substantially as 5 set forth.

2. In a railroad-rail, the combination of the foot and web section A B, having longitudinal vertical groove B, and Side perforations, b b, communicating therewith, with the tread-seo- 1o4 tion C, having depending longitudinal ange C', provided with an inclined-faced side groove,

C2, and the hook bolt D D, adapted to bear against the inclined side of the said groove G2, and nut E, substantial] y as set forth.

In testimony that I claim the foregoing I 15 have hereunto set my hand, at Juneau, in the county of Dodge and State of Visoonsin, in the presence of two witnesses.

FREDERICK W. BROOKS.
